Abstract
A light focusing method, which mainly comprises installing a lens on the outer ring of light bulb of car light to allow light passing through the lens to refract such that the lens acts as a focusing function to allow light beam from the lens project on the reflection mirror at a particular angle in a parabolic trajectory in which radian of the reflection mirror corresponds to the curvature of the lens surface so that light beams emitted from the lens can concentrate on the effective reflection area on the reflection mirror in order to prevent light beams from scattering into ineffective light source so as to increase illumination efficiency of the car light.
